Or a better editor. Modern code editors have affordances to improve readability of such code, such as highlighting matching braces, coloring nested scopes, or folding and unfolding scopes.
One advantage of the editor-based approaches is that they don't make editing more difficult. You don't need to write any scope annotations and you don't need to keep them up to date as the code changes.
